.l 'he Schedule referredto in these Letters Patent and making m of the lame.

To all whom it may concern Be it known that I, THOMAS A. Dnvms, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Lamp-Chimneys for Signal and other purposes; and -I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which-- Figure 1 is a sectional elevation, and I Figure 2 is a side elevation of a chimneyhaviuga red circumferential band.

This invention relates to a new article of manufacture in the form of a lamp-chimney'for head-lights for locomotives.

It maybe made in the "usual form of lamp-chimneys, and is provided with transverse or longitudinal colored bands on one side, so that when revolved on its axis, or raised or lowered by suitable mechanism, lights of correspondingly-diifereut hues will be thrown on the track in front of the locomotive, and thus the desired signal of danger or safety, &c., be given.

The size and shape of the chimney also adapt it to exhibit more than one colored band at the sometime, and thus change in the signal is readily made by properly adjusting the chimney.

Referring to the drawinga is a box, such as is ordinarily used for inclosiug a locomotive head-light.

I b is the lamp which produces the light, said lamp being arranged within the box in the usual manner elther to revolve or remain stationary. v

'lhe chimney is stained in oueor more longitudinal If the circumferential bands are employed the same result is accomplished by raising orlowering the chimney. g

The chimneys of locomotive head-lights are now made of a uniform hue, generally white, and signals of different colors are produced by exterior plates or These I do away with, and simplify the construction of m y head-light by using one chimney, colored as specified.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-- As a new and improved article of manufacture the lamp-chimney for locomotive head-lights, herein de-.
